Design detailsDesign
Fully floodable submersible motor pump Not self-priming Close-coupled pump set
Shaft seal Two bi-directional mechanical seals in tandem
arrangement, with liquid reservoir
Impeller types Various, application-based impeller types
1) For short periods (3 to 5 minutes or until the temperature guards trip) UL and WL models can be operated at up to 80 C.2) In countries stipulating explosion-proof units for handling sewage with faeces, motor version YL must be used.

Product benefits Easy and fast installation/removal with polarised,
absolutely watertight cable and KSB plug connectionensuring correct installation
Motor absolutely watertight, also in the event of damageto the cable sheath, with individually stripped, tinned andresin-sealed conductors
Highest operating reliability with optimum motorselection for operating mode S1, thermal class F,explosion-proof variant in Ex d IIB T4 Gb
Long service life with shaft made of corrosion-resistantstainless steel
Zero maintenance, ideal for continuous duty, with long-life bearings sealed on both sides, grease-packed for life
Environmentally friendly, non-toxic, food-approved oil Significant reduction of energy costs by optimised
hydraulic system and high efficiency Absolutely reliable and non-clogging design with
optimised cutter (S impeller). No risk of leakage with close-coupled pump design Stationary pump sets easy to install and remove with
automatic, bolt-free connection; leakage prevented byelastic sealing elements
Ease of service with wetted bolts made of stainless steel,which are easy to undo even after years of operation
Two bi-directional mechanical seals with oil reservoir filledwith ecologically acceptable oil provide double safety
Well suited for mechanical seal with covered spring forabrasive and aggressive fluids
Only one set of spare parts for all pump sizes thanks tomodular system
